A n s w e r:
1 mole of any gas at STP occupies 22.4 litres of volume.
Therefore number of moles in 1.12 litres = 1.12/22.4
= 0.05 moles of CO2

Why cannot the motion of an electron around the nucleus be determined accurately?
a n s w e r
Because there is an uncertainty in the velocity of moving electron around the nucleus (Heisenberg’s Uncertainty Principle).

Chemical Equilibrium
In a chemical reaction chemical equilibrium is defined as the state at which there is no further change in concentration of reactants and products.
For example,
At equilibrium the rate of forward reaction is equal to the rate of backward reaction. Equilibrium mixture: The mixture of reactants and products in the equilibrium state is called an equilibrium mixtures.

In molecular geometry, bond length or bond distance is defined as the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types, relatively independent of the rest of the molecule. Bond parameters refer to the characterization of covalent bond on the basis of various parameters like bond length, bond angle, bond enthalpy. Bond length is defined as the equilibrium distance between the nuclei of two bonded atoms in a molecule. Bond lengths are measured by spectroscopic X-ray diffraction and electron-diffraction techniques. In the case of a covalent bond, the contribution from each atom is called the covalent radius of that atom.

In algebraic geometry, a nodal surface is a surface in projective space whose only singularities are nodes. A major problem about them is to find the maximum number of nodes of a nodal surface of given degree.

Paramagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field.

According to Boyle’s Law P1 V1 = P2 V2
Here the temperature is constant. Therefore
1.2 X 120 = P2 X 180
OR
P2 = 1.2 X 120 /180 = 0.8 bar
Therefore, the pressure would be 0.8 bar.
